May be a bit of a stupid question but i recently replaced my 1.2 8v corsa spi engine with a 1.4 8v spi but it seems to lack in power if you can call anything 1.4 produces power i am wandering if i have been very silly as i never replaced the e.c.u could this be the source of my woes n e input would be great cheers

Yes, get it changed Asap.
The 1200 ecu is fueling for a 1200cc engine.
Make sure the 1.4 ecu is the right type for your engine(Distributor model, or DISpak)
